Well, keep in mind the problems Debian had with multiple Perl installed at a time and reasons why it changed. Python provides multiple versions but it also provides a dummy package pointing to the standard version of Python. I have a pretty good idea of problems that can arise since I followed such transitions. What must be dealt with: all ocaml binaries must be in sync: you must ensure that you'll never have ocamlc 3.04 with ocamlrun 3.06 for instance ; you must *not* use alternatives, it was the cause of many problems with Perl. The best way is the Python way as explained Stefano with a dummy ocaml and ocaml-base pointing to the standard version of ocaml. Cheers, -- Jérôme Marant http://marant.org
